Cabin AI vs Saydi: event interpreting or everyday conversation?

By Official AppDuo editorial team · Updated

Quick verdict

Cabin AI targets events and shared-earbud conversations, with prices only in-app; Saydi lists prices, offers a Free plan and has more ratings.

Cabin AI comes from ThinkPrompt, the company behind Doctranslate.io. Besides a mobile app where two people share one Bluetooth earbud, it offers Onstage captions for conference audiences and a desktop app for online meetings. Plans are sold by minutes, from 60 to 420 a month, and the mobile app only reached the App Store in September 2026.

Saydi has three modes: two-way translation, one-way translation and transcription with speaker labels. Usage is metered in credits, and Pro costs $9.99/month on the official pricing page. It has been out since December 2025 with more than 1,000 Google Play ratings, but its store descriptions claim on-device audio processing that its own privacy policy contradicts.

Head-to-head

Cabin AI leads on 1, Saydi on 5, 4 even

FeatureCabin AISaydi
Interpreting for conferences and events[1],[2],[6],[9],[14]A dedicated Onstage product: attendees scan a QR code or enter a 6-digit code to follow captions, no sign-in needed.Event and Business plans for organisations are quoted on request; the sources read do not describe how attendees follow along. Screen-audio translation since version 3.0.
→ Organisers who want attendees reading captions on their own phones get a documented workflow with Cabin.
Face-to-face conversation[4],[5],[8],[14]Two people share one Bluetooth earbud and the app detects speech with no push-to-talk; Android adds a split-screen view for people sitting opposite each other.Two-way mode detects languages automatically and labels speakers; two-way voice translation arrived in version 3.0 (15 June 2026).
→ Both handle two-way conversation; Cabin builds around a shared earbud, Saydi around a record of who said what.
Preloading documents and terms[4],[6],[9]Up to 5 uploaded files as context so names and terms come out right (1.0.5 release notes).AI context from documents and custom terms: Free allows 3 terms and 5 MB files, Pro 100 terms and 50 MB, Teams unlimited terms.
→ Both let you prepare before a session; Saydi spells out limits per plan, Cabin only gives a file count.
How usage is metered[4],[5],[9]By minutes: Starter 60, Pro 150, Business 420 a month; the one-time Lifetime plan still caps monthly minutes.By credits: voice-to-text costs 45 credits/hour, voice-to-voice 200 (basic) or 400 (premium); subscription credits do not roll over.
→ Minutes are easier to count, but the sources AppDuo read do not say whether Cabin charges text and voice output differently. On Saydi, spoken output burns credits several times faster.
Paid plans for individuals[1],[4],[5],[9],[14]No prices on the website; App Store and Google Play list only minute allowances, with prices shown inside the app.Pro at $9.99/month, or $95.90/year on the App Store (about $7.99/month). Teams, a business plan, is a separate $19.99 per seat per month.
→ Only Saydi shows a price before you install; Cabin's prices appear only in the app, so the two cannot yet be compared on price.
Trying it for free[1],[9],[10]A free-trial button on the website, with no stated minutes or duration.A Free plan with no card: about 2 hours 13 minutes of voice-to-text in the first month (~100 credits), 10 minutes per session.
→ Saydi tells you up front how much you can try; the 10-minute session cap is enough to test, not to cover a long meeting.
Refunds[4],[5],[10]No dedicated refund policy found; in-app purchases follow Apple's and Google's rules.A 100% refund for an unfixable technical failure on Saydi's side (request within 14 days) or a payment that did not unlock access (within 30 days); duplicate charges are also refunded (within 30 days).
→ Saydi states which cases qualify and the deadlines; with Cabin you rely on the app store.
Platforms[1],[4],[5],[8],[13]iOS, Android, Windows and macOS; the desktop app works with Zoom, Google Meet and Microsoft Teams.iOS, Android, macOS plus Chrome/Edge extensions for Meet, Zoom and Teams; no Windows app on the download page.
→ A native Windows app exists only for Cabin; browser-centred users get Saydi's extensions.
What happens to recordings[3],[4],[5],[11],[14],[16]Keeps audio, transcripts and translations until the account is deleted; third parties handle recognition, translation, speech and hosting. Both store labels nonetheless claim no data collection.Raw audio is not stored permanently; transcripts stay on Saydi's servers only if you save a session. Audio goes to Deepgram and Google, though the store descriptions say on-device.
→ By policy, Saydi keeps less. Both, however, have store declarations that contradict their policies, so do not rely on the labels for sensitive content.
Track record and public ratings[5],[6],[7],[14],[15],[16],[17]On the App Store since 3 Sep 2026 with no ratings yet; 100+ downloads on Google Play; no Product Hunt reviews.Out since 18 Dec 2025; 4.5/5 on Google Play (1,250 reviews), 4.22/5 on the Vietnam App Store (812), 4.4/5 on the US App Store (16); no Product Hunt reviews.
→ Saydi has user feedback to go on and Cabin does not yet; neither has an independent accuracy test.

Choose Cabin AI if…

  • You run conferences and want attendees reading captions on their own phones
  • You often host foreign guests and like handing them an earbud and just talking
  • You join Zoom, Meet or Teams calls from a Windows PC and want an installed app

Choose Saydi if…

  • You want to see the price and try it free before paying
  • You need meeting transcripts with speaker labels and a summary
  • You translate only now and then and prefer top-up credits that never expire
  • You prefer an app with plenty of store ratings behind it

A conference hall or a meeting table

The clearest difference is scale. Cabin splits into three products for three settings: Onstage for halls, a desktop app for online meetings and a mobile app for in-person talks. Its website lists events that have used it since 2025, including Vietnam Innovation Summit 2025. The mobile app also has group rooms and an Ask Cabin AI button for conversation summaries. Saydi is built around translating and recording the conversation: translation, transcription, summaries and an in-session chat, plus browser extensions for calls. Since version 3.0 it can also translate audio playing on screen. Saydi does have an Event plan, quoted on request, but the sources AppDuo read do not explain how it works for an audience.

Minutes, credits and the costs you cannot see yet

With Cabin, the first question is the price, and you can only answer it after installing the app. Minutes are clear: 60, 150 or 420 a month, and even the one-time Lifetime plan has a monthly cap. With Saydi the price is public but the maths is yours: Pro's 1,000 credits cover roughly 22 hours of voice-to-text, or only about 5 hours if you listen to basic spoken translations. Subscription credits do not roll over, while top-up credits ($2 per 200) never expire. For short trips, the App Store also sells 3-, 4- and 7-day Trip Packs at $4.99–$7.99.

Where the conversation ends up

A voice translator hears the whole conversation, so its data policy matters as much as its accuracy. Cabin's policy (updated 10 Aug 2026) rules out training its own models or advertising on the data and offers in-app account deletion; however, audio is kept for your history until you delete the account. Saydi names its processors, Deepgram and Google, and says neither retains audio. The shared worry is the self-declared store information: Cabin's labels claim no data collection, Saydi advertises on-device processing, and Saydi's Google Play form even says data is not encrypted while its App Store label lists usage data used for tracking. AppDuo's research records no breaches, lawsuits or complaints for either app as of 13 Nov 2026.

Who is behind them and how proven they are

Both have Vietnamese ties. Cabin is made by ThinkPrompt Company Limited in Vietnam, the company behind Doctranslate.io. Saydi is listed under Notionis Technologies Pte. Ltd. (Singapore) on the App Store, while its terms are issued by SotaX Company Limited, which the website names as its operator in Vietnam. Saydi has reached version 3.12 in under a year; Cabin's mobile app reached the App Store on 3 Sep 2026, and its latest iOS version is 1.0.5 (11 Nov 2026). Neither publishes latency figures or has an independent accuracy test, so before an important session, run a trial with your own language pair and terminology.

Frequently asked questions

Which one covers more languages?

Cabin claims 80+ languages on its website and 100+ on the app stores. Saydi says it supports 60+.

Is the app interface available in Vietnamese?

Saydi's App Store listing shows 10 interface languages, Vietnamese included. For Cabin, the App Store lists English as the app's only language, although the website comes in Vietnamese, English, Chinese and Japanese.

Can I pay in VND?

The sources AppDuo read show no official VND price for either app. Saydi's pricing page lists USD only and Cabin shows prices only in the app, so check what your store account displays.

Does either work fully offline?

The sources AppDuo read describe no offline mode for either app. Both privacy policies say audio is sent to outside services for recognition and translation; Saydi's on-device claim in its store listings does not match that policy.

What if I run out of minutes or credits mid-month?

Saydi sells top-up credits, even without a subscription. The sources AppDuo read do not say whether Cabin sells extra minutes.
